Hello Rancher experts, I wanna setup 3000 nodes cluster using rancher community edition. Need to some help to understand how we can achieve this. How many clusters are recommended to handle 3000 nodes in production, how many control plane nodes are required for each cluster and do we need etcd node separately or on control plane itself. Please help me to design this architecture

This sounds like exactly the sort of large scale exercise you'd want to pay for support and consulting on.

Actually we are not in the position of paying huge amount, that's why planning to use community edition. RKE2, I wanted to create and manage clusters on multi cloud env.

sharing that sort of expertise and guiding companies through deploying products at scale is literally what we sell. its what pays the developers that make it so that we can offer the software as free open source.
